So presuming I can require haml or something and overcome this error,
how would U check the output? Obviously this spec was written
expecting the display_flash helper to return a string (which it used
to do), by using open it now presumably renders directly to the haml
buffer, so how would I retrieve that so I can test it? (Remember this
helper spec runs without using actually using a view).
Thanks
